Tonnage Formula:
| From: | To: |
AC compressor tonnage refers to the cooling capacity of an air conditioning system. One ton of cooling equals 12,000 BTU (British Thermal Units) per hour, which represents the amount of heat required to melt one ton of ice in 24 hours.
The calculator uses the simple formula:
Where:
Explanation: This calculation converts BTU rating to equivalent tons of cooling capacity, which is the standard measurement for air conditioning systems.
Details: Correctly sizing an AC unit is crucial for energy efficiency, proper humidity control, and system longevity. Undersized units struggle to cool spaces, while oversized units short cycle, reducing efficiency and failing to properly dehumidify.
Tips: Enter the BTU rating of your AC unit. The value must be greater than 0. The calculator will instantly convert it to tons of cooling capacity.
Q1: What is the relationship between BTU and tons?
A: One ton of cooling equals 12,000 BTU per hour. This measurement originated from the amount of heat needed to melt one ton of ice in 24 hours.
Q2: How many BTU do I need for my room?
A: As a rough estimate, you need about 20 BTU per square foot of living space, but this varies based on ceiling height, insulation, climate, and other factors.
Q3: What's the typical tonnage for residential AC units?
A: Residential units typically range from 1.5 to 5 tons, with average homes requiring 2-4 tons depending on size and climate.
Q4: Can I use this for heat pumps as well?
A: Yes, the same calculation applies to heat pumps as their cooling capacity is also measured in tons and BTU.
Q5: Why is proper sizing important?
A: Properly sized units operate more efficiently, last longer, provide better comfort, and maintain appropriate humidity levels. Oversized or undersized units can lead to higher energy bills and reduced comfort.
